Witilt v2.5 code builgin problem

Dear all,

I’d like to ask for help about the building of witilt v2.5 code. The witilt v2.5 can be downloaded at http://www.sparkfun.com/Code/WiTilt_2_5.zip.

I cannot compile witilt v2.5 using WinAVR, I’ve already compiled successfully in witilt v3.3 but failed in witilt v2.5. Because of no makefile in witilt v2.5 code, I do not know how to start to build the witilt v2.5 (I am also a newbie in AVR code).

Could anyone help me in compiling witilt v2.5 code?

Very appreciate!
